A functor is constructed from the category of globular CW-complexes
to that of flows. It allows the comparison of the S-homotopy
equivalences (resp. the T-homotopy equivalences) of globular complexes
with the S-homotopy equivalences (resp. the T-homotopy equivalences)
of flows. Moreover, it is proved that this functor induces an
equivalence of categories from the localization of the category of
globular CW-complexes with respect to S-homotopy equivalences to the
localization of the category of flows with respect to weak S-homotopy
equivalences. As an application, we construct the underlying homotopy
type of a flow.
